A T-shirt in the oil pan? WTF? The vacuum from the oil pickup probably tryed to suck up the t-shirt and caused the oil to accumulate in the pan and not get circulated.

If the motor still turns over with no "noise" and by noise I assume you mean compression then you have no compression. Which means air is bypassing the piston or your valves which branches off to alot of different problems. Are these interference motors?

no dude it happened like this

1. winter rebuild - found a tshirt in my pan - took it out
2. saw that the pickup wasnt tight in there -thought its normal
3. put new oil bla, finished the bike, synced the injectors bike was running like a pimp
4. blew the engine the second day of riding
